Tolall whom 'it may concern.'

Be it known that I, EDWARD C'oNnoYNNI,

a citizen of the.United States, residing at New York, county of New York, and Statev of New York, have invented certain new and useful Improvements in Aeroplanes, of which the following is a specification.

' -The object of this invention is to provide a new and improved construction of an aeroplane which 1s capable of `"being operated to ascend in a vertical direction similar to a helicopter, which may be held stationary in l the airor which may bef operated forward or backward along horizontally extending 'planes or planes inclined to the horizontal.

Another obj ect 'is to provide such an aero- I p ane with a single motor` and a plurality of propellers operated thereby and by means of which the manipulation of the aeroplane may be largely controlled.

For the accomplishment of these and such furtherV objects as will be apparent t those skilled in the art topwhich this appertains, my invention consists in the construction, combination and yarrangement of parts, a preferred .embodiment of which is hereinafterJnore specifically described and illustrated in the accompanying drawings forminga part thereof but it will be understood that changes, variations and mod' cations may be resorted towithout departi g from `the spirit of my invention.

. Referring to thedrawiiigs:

Fig. l is a side elevation of an aeroplane, part of the hull being broken away to show the propeller clutches, and

Fig. 2lis a plan view partly broken away.

As 'shown inthe drawings the numeral 10- indicates the fuselage, ,in which the engine 11 is secured. A main driving shaft' 12 eX'- tendslongitudinally of the yfuselage '10, and' -is provided with a pulley 30 about which,

and a pulley 31 secured to the engine shaft 32, a belt33 is trained. The endsof said shaft project outwardly beyond the fuselage and'have secured thereto the propellers 13 and 14., A secondary vertically extending .'oower shaft '15 is` driven from 'the main shaft 12 by means of the bevelgearing 16` and is rotatably supported in the bracket 17.

Clutches 18 and 19 provided with suitable actuating handles are interposed between the enginezand the propellers-13 and 14 re.-4 spectivelywhile. a third clutch 20 is interposed between a propeller`21 secured vto'the end of thefsecondaryshaft 15.

' Suitably secured to the fuselage 10 and extending laterally therefrom are two sets of wings orv planes 23, and 24 each set consisting of a pair of parallel horizontally extending planes. A plurality of dele'cting wings 25 arepivotally secured to the sides of the fuselage and are provided with suitable controls to enable them to be readily actuated from the cock-pit .of the machine. A plurality offascensional blades 26 are pivotally secured upon'the horizontal aXes 26a tocontrol the ascent or descent of -the machine. A a

Ground .wheels 27 are mounted as by means of the framework 28 to the bottom of the fuselage in the usual and well known manner. I

The operation,l of the aeroplane is as follows: AIf itis desired to cause the machine "to rise vertically, the engine 11 being start-\ ed, clutch 20 is thrown into space to put the propeller 2lvin operation and if the lifting power o f this propeller is insufficient to cause the machine -to' rise, both of the clutches 18 and 19 are thrown in to start propellers 13 "and 14.. As these propellers areconstructed and arra-n d toproduce a 1 driving thrust in opposite directions, the air lcurrents produced thereby will impin'ge upon the `planes 25 and sufficient additional lifting force will thus be brought )into op'- eration to insurefthe rapid ascent of the machine. f

If it is desired to make anangular ascent "eitherof the propellers 13 or 14 may be rotated, and the additinal lifting power of the propeller 21 may also be used if desired. By manipulating the deflecting wings 25 the direction of the machine to the right or left may bechanged as desired.

If it is desired to maintain the plane stationary in the air the both propellers 13 and 14 are rotated or all three propellers 13, 14 and 21 are rotated, the enginer being throtfled down to the proper vspeed tokeepfthi g 4 plane from ascending-- c Having thus described my invention, what lI claim as -new and `.desire to secure bygLet ters Patent, .is f n 1. fAn4 aeroplane having .a fuselage, an engine mounted 'within said fuselage, a main driving shaftfa. pair of oppositely act-L ing propellers secured to said shaft adapted to exert horizontal oppositely 'directed driving thrusts to said fuselage, a pair of planes secured to said hull adjacent each of said said hull.

2. An aeroplane having a fuselage, an 'en-x ginermounted within said fuselage, a main driving shaft, means operatively connecting said engine and main shaft, said main shaft extending in` alignment with the longitudinal center of, and projecting beyond the ends of said fuselage, a propeller secured to the each of the projecting ends of said shaft, the

propeller on one endof said shaft construct- 2Q ed and arranged to exert ahorizontal driving thrust opposite in direction to the propeller on the opposite end thereof when said shaft is rotated, a pair of horizontally extending planes secured to saidhull adjacent each propeller toreceive the air currents caused by the rotation thereof, a secondary shaft located substantially centrally of the ends of said main shaft and extending perpendicularly thereto, `a third propeller secur d to the end of said secondary shaft and a clutch interposed between each of said provpellers and said engine to enable said pro-l pellers tov be selectively placed infoperation. 3. An aeroplane having a fuselage, an engine mounted Within lsaid fuselage, a main driving shaft, a vpair of oppositely acting propellers secured to said shaft adapted to exert horizontal oppositely directed driving thrusts to said fuselage,. a pair of Iplanes secured to said hull adjacent each ofsaid propellers, a thirdnpropeller, a vertically extending shaft upon which said third propeller 1s mouited, 'means to operate said vertical shaft from said main shaft, means'to selectively operate said propellers from said engineand aplurality of ascensional blades plvot-ally secured upon horizontal axes to the sides of said fuselage. Y

.4. An aeroplane having afuselage, an engine mounted withinsaid fuselage, a. main propellers secured to said shaft adaptedto exert horizontal oppositely directed driving thrusts to said fuse cured to said hull adjacent each of said proage, apair of planes sepellers, a third propeller, a vertically extending shaft. upon .which said third propeller 1s mounted, means to operate said vertical shaft from said main shaft, means to selectively operate said propellers from said engine, a plurality of deflecting blades pivotally secured upon vertical, axes to the sides of said fuselage, means to move said defiectorst'o extend in parallelism with or laterally from said hull and a pluralityL of ascensional blades pivotally secured upon horizontal axes tothe sides of said'fuselage.
